Evaluate -(7-³)(7⁵)

A. -49
B. 49
C. 1/49
D. - 1/49

Greetings from Brasil...

Let's apply the given formula:

A = (1/2)·B·H

The base of this polygon (in this case, the triangle) is B

B = X² - 2X + 6

The height of this polygon is H and is H

H = X + 4

Applying these values (B and H) in the given formula.....

A = (1/2)·B·H

A = (1/2)·(X² - 2X + 6)·(X + 4)

A = (1/2)·(X³ + 2X² - 2X + 24)

A = (X³/2) + X² - X + 12

OR

A = (X³ + 2X² - 2X + 24)/2

Answer:

First find hypotenuses

Step-by-step explanation:

First you must find h by using formula

A^2+b^2=c^2 when you find this you already given base and put the c you find is h and b is given in the formula you will get area

Answer:

They only put 1 base instead of 2 bases, so its D

the real answer is 156pi = 489.84

Step-by-step explanation:

the fireplace would have 24 bricks on the 10th row

Answer:

27 bricks

Step-by-step explanation:

y= 54- 3(x-1)

y= 57- 3x

is the function, y= number of bricks on the xth row, x= row number above the bottom one

x=10 ⇒ y= 57 - 3*10 ⇒ y= 27 bricks

Answer:

D and then D

Step-by-step explanation:

3.30-2.84=0.46

0.46/2=0.32 (because two years)

this is negative because it is a decrease

3.68-2.84= 0.84

0.84/2= 0.42, which is higher than all the others

Explanation:

The probability of drawing two red playing cards in succession from a preferred deck of playing cards is 1/4

The opportunity of drawing a red card on the first draw is 26/52 because there are 26 red cards out of a complete fifty-two playing cards.

Since the first card is replaced, the deck remains the same for the second draw. Therefore, the probability of drawing a red card on the second draw is likewise 26/52.

To calculate the probability of two unbiased occasions going on, we multiply the possibilities of each occasion together:

P(2 cards are red) = (26/52) * (26/52)

Simplifying:

P(2 cards are red) = (1/2) * (1/2)

P(2 playing cards are red) = 1/4

Therefore, the probability of drawing red playing cards in succession is 1/4.

Step-by-step explanation:

since it tells you 4 students does homework does more then one hour and 20 students were questions there is a chance that the other students who answered will take less time. A mode is when one number appears the most in your case it’s the number of students that appears the most in you line plot. Example: 2 students take one hour (put 2 dot on one) 5 students take 2 hours (put 5 dot on two hour) and 1 student takes 2.5 hours (put a dot on 2.5) then the mode for this example the mode is 5

Answer:

Hello, for the first one, the answer should be (C) 3

The following transformation is an enlargement, meaning it would get bigger. Meaning that the scale factor increases by 3.

2x3=6

3x3=9

Therefore, the scale factor is (C) 3.

#5: The answer is (D): 4

Since this is an enlargement, we have to determine what ? x 6 = 24 is. Since the height of the photo is 6, we can conclude that 6 x 4 = 24.

Therefore, the answer is (D): 4

Answer:

The Eagles lost 2 yards

Step-by-step explanation:

Say The Eagles are on the 50 yard line, they lose 13. Now sitting back at the 37 yard line, they run a play that gains them 18 yards, putting them on the opponents 45 yard line. Then they lose seven yards moving them back to their 48 yard line. only losing two yards from where they started

Answer: Total yardage was a loss of 2 yards.

Step-by-step explanation: Losses

-13-7 = -20. Gain +18

Compare or subtract 18-20= -2

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143
